将数据从活动传递到片段而没有替换片段的问题
我的代码如下，但数据未从activity传递到fragment。我不知道为什么！
活动：
public class ScrollableTabsActivity2 extends AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
private Button logout_user;
//private SQLiteHandler db;
private SessionManager session;

String value="";
String numero_tavolo="";
ArrayList<Integer> hm3=new ArrayList<>();
ArrayList<Integer> hm_quantitàpizze=new ArrayList<>();
TextView numero_tavolo_text_view;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_scrollable_tabs2);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
txtName = (TextView) findViewById(R.id.name);
txtEmail = (TextView) findViewById(R.id.numero_telefonico);
numero_tavolo_text_view=(TextView)findViewById(R.id.numero_tavolo);
logout_user=(Button) findViewById(R.id.crisbio);
logout_user.setOnClickListener(new View.OnClickListener() {

}
});
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
viewPager = (ViewPager) findViewById(R.id.viewpagerr);

tabLayout = (TabLayout) findViewById(R.id.tabss);
tabLayout.setupWithViewPager(viewPager);
Bundle extras = getIntent().getExtras();

System.out.println("FILE:" + file);
FileInputStream is = null;
try {

} catch (FileNotFoundException e) {
e.printStackTrace();
}

}
Element element = doc.getDocumentElement();
element.normalize();

if (node.getNodeType() == Node.ELEMENT_NODE) {
Element element2 = (Element) node;
//tv1.setText(tv1.getText()+"\nName : " + getValue("name", element2)+"\n");
String id = getValue("id", element2);
a = Integer.parseInt(id);
String idd = getValue("quantita", element2);
b = Integer.parseInt(idd);
System.out.println("XMLLLLLLLLLL:" + b);
hm.add(a);
hm_quantitàpizze.add(b);
System.out.println("AZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ:" + hm_quantitàpizze);
System.out.println("LAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA:" + hm);
}
}
Bundle bundle = new Bundle();
bundle.putIntegerArrayList("oki", hm);
bundle.putIntegerArrayList("okiquantitapizze", hm_quantitàpizze);
System.out.println("OGGETTO BUNDLE:" + bundle);
MyListFragment2 myFragment = new MyListFragment2();

}
numero_tavolo_text_view.setText(numero_tavolo);
}
片段：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
System.out.println("BUNDLES prima:" + bundle);
bundle=getArguments();
System.out.println("BUNDLES dopo:" + bundle);

strtext2 = bundle.getIntegerArrayList("oki");
System.out.println("BUNDLES1 dentro:" + strtext2);
quantitàpizze2 = bundle.getIntegerArrayList("okiquantitapizze");
System.out.println("BUNDLES2 dentro:" + quantitàpizze2);
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the custom_spinner_items for this fragment
//super.onDestroy();
SharedPreferences settings = getContext().getSharedPreferences("states", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = settings.edit();
editor.clear();
editor.commit();
ViewGroup rootView2 = (ViewGroup) inflater.inflate(R.layout.fragment_list_2_2, container, false);
return rootView2;
}

错误是：
BUNDLES dopo：当我尝试传递数据时为空
非常感谢您在这件事上的时间和帮助。
